Sorry, but that is not an excellent solution.

1. It voids your warranty.
2. Apple will not support your phone any more and you will have problems updating to the latest version of the OS when it is released (which really is NOT a good idea given the SMS hack that was demo'ed at the Black Hat meeting yesterday that is going to need to be patched asap).
3. OmniGroup and other developers have no idea what other hacks you are using on your phone and what other processes are running at the same time, so it makes it exceptionally difficult for them to support you when things start going wrong.
4. Apple are not lying when they say that gaolbreaking is a source of many issues (apps crashing, notifications not working properly, etc) for people who do it.
5. It will make your battery drain faster.

Etc.

It would be an excellent solution if Apple officially permitted (some) background processes for third party apps, shorter battery life notwithstanding, but hacking your OS is not it.
