So the other day I dropped and cracked the bottom left corner of my iPhone 4 :'(. A day later it started saying "no sim card installed" so I restarted it and it fixed the problem for a bit then it happened again so I took it to the apple store. The lady reset he network settings (Didn't even think to do that) and it fixed it until today when it happened again. So I went back hoping to get a replacement phone and the guy I talked to said it was a "known problem" with the sim card being read and apple would have a firmware update to fix the problem in about 6 days. #1 Apple is hard at work with 4.1 betas so I highly doubt there will be a "fix" in 6 days #2 He said oh Just pop out the sim card and pop it back in..... uhhhhhh I'd rather just have my phone work in the first place #3 Do you think I should go back and demand another phone even though he claims it wont fix the problem by switching phones?
