TP2: Verizon vs Sprint vs Tmobile vs AT&T

[monkeyboy]

I'm trying to decide which version of the TP2 to get, as my "other phone". That is, I want to use it on multiple carriers, definitely GSM carriers, both domestically and int'l, but maybe also CDMA carriers (e.g. PagePlus). Also I'd like to know any important "gotchas" for each version. So could someone give me a quickie run down on the important differences between these TP2 versions? generally, but also here are some specific questions:

- I gather that both CDMA versions are locked for each carrier's GSM int'l roaming SIM, but that at least the Verizon TP2 can be fairly easily unlocked. I *definitely* want to use this TP2 with both Tmo and with random int'l SIMs. Can the Sprint version also be unlocked as easily?

- The Tmo and AT&T versions support different 3G bands. Remind me how this might affect usage int'lly... I think there is little chance that I will want to use the TP2 on AT&T, but I definitely want Tmo and, say Europe and Japan. I don't think I care about Tmo's 1700Mhz 3G band.

- Any other major diffs? JVM support (does Verizon's come with a JVM? I presume it is easy to add)? TV Out? (do all have it?)

thanks...
