Im about to get this phone either tomorrow or monday. I have a few questions to ask. It is also my first smartphone.
1) I like HTC's widgets design, can I also have it on the O2X? or its exclusively for HTC only?
2) Is the battery life good? I never had a smartphone before, so i dont know how to compare but my brother has a 3gs , is it better than that ?
3) Is it worth to install custom ROM for the phone? Since i heard it voids the warranty.
Thanks for answering my questions, i hope you guys understand my situation as a first time smartphone user.
1.HTC's widgets is from HTC own UI named HTC Sense.
Its beauty and usefulness is popular among manufacturer custom android UIs.
However, you can have some beautiful clock/weather widgets on this phone too.
Just get the 'Beautiful Widgets' from Android Market and you're set

2.The battery life is depend on your usage, 3G network consumes battery faster and make the phone hotter.
Excessive gaming/video playback also consumes a lot of battery.
Other than that, casual net surfing, music playback, texting, calling is not a problem.
3.Custom ROM improve lots of performance and you can even tweak it with your likings.
However, Stock ROM is not encouraged (unless you're on V10C or V10D)
There're few custom Roms now:
MoDaCo Custom ROM. [Various changes and improvements]
MoDaCo Vanilla Custom ROM [Everything is almost like a pure Google phone..]
Cyanogen Mod 7.1 Nightly #5 (Experimental Mod- Not recommended, but it's runnning the latest Android v2.3.4 and it's the most popular custom ROM of Android, I recommend you to wait until its stable release, you'll love it

)
All I said is just my opinion .. Just wanted to help

This is also my first smartphone though, I spent a lot of time playing it

But actually inside my phone there isn't any games LOL
