According to the specs here is does support UMTS 900, so yes.Will it be possible to use your Speedstick sim card in a Samsaung Galaxy Tab 10.1v or any of the other tablets?
1. Yes. The iPhone 4 fully supports 900mhz 3G, unlike the 3G and 3GS. I've tested it, works fine.
2. Yes. You need to have 3G coverage, which not the whole country has, otherwise you're back on 2G.
3. Yes. Works really great.
I do not see the personal hotspot feature in my "settings" on the iPhone
