So, check this out. I recently purchased a few auxillery items for my HTP2, even before I actually had it in hand. One was a rubberized case for it. You know the type, the 2-piece hard plastic with the rubbery texture. Well, suffice it to say, it was just slightly too small for my US T-Mobile HTP2. Try as I might, I could NOT get it to fit. I almost scratched the crap out of my phone trying...
Ok, so I figured that it was maybe a manufacturer problem right? the 1-1,000 that quality control missed. So I ordered another one from a different vendor. STILL too small... Thus, I scrapped the idea.
So, heres the best part. The charging base for my HTP2 just came in from Hong Kong. Guess what?! The area around the charging post IS TOO SMALL FOR THE PHONE. Not a lot, but just enough that it woun't make a solid connection, or seat properly. I had to modify the hell out of the base in order for it to seat my phone enough to actually make it accept enough of the post to charge it. Its on there right now, so I'll let you know if it actually charges as it should, even though its not seated properly.
Conclusion, after seeing a friend of mines' HTP that he got overseas a week before I got mine, I noticed that they are not the same size. The US version is, in fact, thicker than the european model.
This leads me to a few more concerns. I just ordered the Invisible shield for my phone from Zagg. Will it fit the US version?

We will find out when it arrives.
It seems that anything that supposed to fit the HTP2 physically was modeled for the European version, not the US version.
Consider yourself warned!
