Following the update of my iPhone 3G to ios4, OmniFocus for iPhone has once again started to misbehave during Bonjour sync sessions. A recurring problem is the iPhone dropping my wireless connection during syncs. I have tried deleting the app and redownloading from iTunes. Although wireless bonjour works fine to start the sync session (the iPhone can see the mac server etc), the iPhone drops my wireless connection when transferring the mac based omnifocus database to the phone. I have archived old actions on the mac and tried rebuilding the database, all to no avail. Has anybody else seen this problem and found a fix?

Hi Calumma

I too updated my iPhone 3G to iOS4 and had to hack it back to iOS3 as it was unusable. It's rumoured that iOS4.1 may fix some of the problems that 3G owners have found in upgrading, but I don't have any idea when Apple will be releasing it.

In the meantime, have you looked at this thread?

I'm (painfully!) aware of the issues with ios4 on the 3G, but am sticking with it for the time being for the unified email inbox.

I looked at that thread, but it seemed to be more concerned with *auto* syncing. My problem is that I can't get the iPhone to sync at all.

Calumma,

You have my sympathy re: upgrading your 3G to iOS4. I had a complete rant about Apple over this, and other issues, in the Omni Lounge.

As you wait for wiser minds than mine to come online and give you the benefit of their experience, in the interim I'd email the Support Ninjas.

The only other temporary solution I can think of is to download a 60-day free trial of MobileMe and sync over that until the issue is resolved.

Sorry not to be more helpful.

.

I do use MobileMe, but haven't used it for OmniFocus syncing, because I assumed the bonjour wifi syncing would be faster... I'll give my MobileMe account a go.

Hi - my first post here (so "hello"!....)

I've found sync (Bonjour) issues as soon as changed to OS4 on the iphone. No improvement with 4.01

Issues: Start up Omnifocus on iphone (fresh startup) and it will find the database on the mac no problem.
Leave from this wireless network and come back - can't find database.
I also work in different locations (different wireless networks) but with same imac brought to that desk (home + work). Try to open Omnifocus after move and resync without any other changes and cant find it.
Temporary Solution found:
Double click the home button to bring up recently launched apps (you know the "multi-tasking" section... yeah, right....) hold down omnifocus icon (or any others) until you can select the "x" to close it. Now reopen a "fresh copy" of omnifocus and it regains the correct wireless link and connects.

I'm guessing with the change to "multitasking" or some new wireless access tweak its effecting the ability of omnifocus to remember the wireless access settings. Perhaps a change is needed in omnifocus itself to work better with the new os4 - I dont know...

Have found the ability of iphone to "automatically" know and connect to a known wireless point a lot weaker since the os4 upgrade. Does drop sometimes and even ask for a password again for a connection its already been set to join.

Hope that helps. -David

I have seen this for ages - way over a year - relatively consistantly and with 2 different iPhones and different MacBooks...

I have Bonjour based sync working fairly well.

However fairly often, I start up OmniFocus on the iPhone, and either just let it sync or force a sync, and you can see the WiFi icon on the top of the display wink out and be replaced with a mobile network connection (normally GPRS at this particular location).

Sometimes you can regain wifi by going to the prefs app and selecting the wifi network, often it appears that you have to kill OmniFocus off (at least in iOS 4), get wifi and then restart OmniFocus to get a successful sync attempt.

It really feels as though there is a correlation with OmniFocus and getting knocked off the network. Even more so there feels like a correlation between a second or subsequent sync session (ie after a weekend I tend to have changes on the phone, so I sync them back, do my weekly review etc, and then sync again) and this form of sync failure....

Other than this I have no problems with WiFi usage or with sync...

Oddly I tried using MobileMe sync for a while due to this, and I seem to get the same effect of knocking the phone off the WiFi network, but the sync still succeeds if somewhat slowly...

Sounds wacky, has anyone else seen this?

That sounds a little like the problem described in calumma's Sync Issues thread, which seemed to be caused by an unreliable Wi-Fi network being overloaded by too much local traffic. I guess I'd start by checking your Wi-Fi router's logs to see if it has any additional information, or perhaps your iPhone's console logs (which you can access using Apple's iPhone Configuration Utility).

My wifi network is perfectly reliable thank you. The only software that I experience issues with is OmniFocus on the iPhone. I can move GB of data between different macs on my network without problem, yet a simple ToDo app on my phone causes the network to fail. As others have also reported, turning on Airplane mode on the phone and manually reconnecting wifi, enables sync to function.

nigelm go into settings and turn on airplane mode. Then manually reconnect to your wifi network, reopen OmniFocus and retry the sync. Let us know if this works.

Looking at the iPhone console logs you can see it dropping the connection to WiFi although not a lot of indications why.

As calumma suggested, putting the phone into airplane mode, enabling WiFi, and syncing always works - and very quickly. It is of course re-establishing the WiFi link when this happens. However when airplane mode is switched off (WiFi still on or just started if I had not explicitly started it in airplane mode), then OmniFocus goes back to very sluggish sync, and a tendency to knock the phone off WiFi entirely (leading to no sync).
