I've gotten 3 different sim cards in the last couple of weeks. One came with a G2, it's got the wider gold contacts on it. The other is a replacement due to a lost phone and has a smaller foot print, then I got a new mytouch 4g and it is yet another design. See pictures. they are all TM 9703, but all have different numbers on the front. I ask this because the newest Mytouch, using the sim that cam in the box, is actually getting steady 3g when no HSPA is available while the other two sim cards I've used in both the mytouch and G2 have not yielded a 3g connection. Anyone have any insight into this?
