ugh..before the hero, i was using a razr v3 lol...but only because of the following....my first smartphone was a t-mobile MDA (not sure the actual HTC model). i loved that phone, despite the winmo crap i put up with. then they came out with the t-mobile wing. junk does not even begin to describe that phone..htc/t-mobile seriously crapped that one. that phone made me despise smartphones, and then i went to a sony ericsson for the first time ever, being sick of carrying around some big ass crap phone. i got the w760a from ATT...after having that phone replaced 3x and my 4th one failing, i snapped it in 2 and bought a razr v3 from hong kong to get me through my contract, which it did!
as for my t-mobile wing, now that i've actually put a decent rom on it, it makes a good pda, but that's about it. and it's a very basic rom. but thanks to the xda folks, that phone works like it never did before. now i have my hero so that thing rarely gets turned on.
