this is the 2nd SE phone after T637, and this phone is just betterusing it with T-Mobile, it works pretty well as phone and modemvoice: the strongest part, the best sounding phone I ever used in 6 years, the speakerphone is OK, not so loudreception: another strongest part, with T-Mobile, it can get some weak signal when all other don't get signal at all; however, the antenna is located at the top back (where the loop is), touching this part will lose receptionoperation: typical SE style, pretty easy for SE users, 3 dedicated buttons: web, messaging, taskcam: excellent, even though it doesn't have auto-focus like K750 and K790, it looks pretty good, even it's better than nokia 6270bt: very easy to use and pair, with pc suite installed, file transfer and sync is just a piece of cake, the transfer speed is 300-400kB, this is the maximum of bt 2.0 speedscreen: the main screen is pretty bright, even I have to set the brightness down, animated standby screen is simply cool; external screen, however, is monochrome (it maybe a plus when using outdoors, the main is barely viewable under sunlight), it display info only, it's a kinda inconveient when doing self-picaudio player: I seldom use it because it doesn't support ogg vorbis, which I mainly use, streaming audio supports real only, no shoutcastconclusion: this phone is a pretty good phone for the price, quad-band is a must for Cingular users, fast EDGE modem for web and tetheringscore: I give it 95/100, there're some consrare memory card (M2), and it's not hot-pluggablelack of ogg vorbis and shoutcast supportno default USB mode (always asks when plug in, kinda annoying)
