In the past few weeks we've seen Apple approve some crazy apps and updates into the App Store. The apps and updates I'm talking about are the ones that are normally available to Jailbreak users, while Apple normally declines them. Apple seems to have become more lenient on their app approval policy.
This week, Apple approved Google Voice back into the native App Store. This shocked many, and then the other GV clients started coming in. Other apps like Handy Light(now removed) which allowed tethering hidden in a flashlight app were approved as well, and who know, maybe Apple approved them to make a few people who were lucky to get it while it was out, happy.
With Apple's newest iOS updates coming out, which have features that the Jailbreak community has had in the past. Long awaited; Multitasking, Video Camera, single contacts SMS tones coming. It looks like Apple might be fighting back.
