1 of the reason is other competitors r keeping up pace dy...
HTC HD2 also hav 5MP, capacitive touchscreen(not as sweet as iPhone 1, but no doubt best in WinMo for now)
in terms of interface of coz...u wont notice much change....
Hardware wise, there would be bigger jump this time

January should see the iTablet/iMac Air(some1 call it), iphone 4G should come at mid year, probably the same time for Verizon to announce as new provider.

ignore the staff...not all staff are properly trained or properly fed with knowledge
tats y best is do ur homework, then go jz fill and sign...not a word wit them at all

btw, u don need take SIM out, all u need is switch on airplane mode
