Recently I have started having some odd problems. It started about 2 weeks ago when my sim card randomly decided to die on me. Tmo replaced it with one of their "new design" sims which is supposed to be more resistant to dis colorization. From the first time I put the new sim in, my phone will randomly not recognize my google account and I will have to log back in. It is starting to worry me. Anyone having this problem or know what it might be. Also on a side note, I have noticed that the new sim cards only have 3 contact points, the phone, and pretty much every other phone has 4. Could this be part of the problem or does it not matter?
