Considering there are alot of devs here, i think they should have look to this. Its pretty cool, and acording to the dev, it can work not only on jailbroken phones, but also respecting Apple sdk rules http://code.google.com/p/networkpx/wiki/GriP P.S.: i have it running on 3.0 beta 4, flawlessly
Did you read the whole thing? Towards the bottom is a specfic section for devs following the SDK and what limitations you will have, but still following the rules. Jailbreakroken version of this is just a lot better because you aren't sandboxed to just one app.
