IF apple enables a cellular connection there is no way they're going to use a sim tray. It's going to be their imbedded SIM and it will be part of the S2 (or S3) SoC.Yes, thinner is good. No space left for a GPS and sim card tray I guess. Battery life is good as it is.
Anyway I won't be buying a new one. The price for this thing is not worth the benefit it returns.
Also thinner.. sounds like the bands won't fit anymore. If they do that I think a lot of customers (like me) will be mad and never buy bands again.
