I am running a jailbroken 2.2 iPhone 3G, and I am having an issue with updating the applications I have purchased through the app store. While on my phone, the little number appears in the top right corner of the app store icon telling me that some apps have updates, except once I go into the app store and look at the updates section, I get the message that says all my apps are up to date. But when I go on my computer and look at iTunes, I can see that I have plenty of apps that need an update. I'm almost positive that this is caused by the jailbreak because I never had this problem before. Is there a fix for this? All help is greatly appreciated.
