on the Suncom network here in Fayetteville, NC and my call quality 28314 is EXCELLENT. period. the inside display is BRILLIANT...i mean you upload any of your photographs and the display is so photo realistic because of the 24bit (16 million- One byte (eight bits) per channel gives 256 (28) intensites for each of the channels which gives 16,777,216 colors for each pixel (often approximated as 16 million despite the fact that it's closer to 17 million). The human eye is popularly believed to be capable of discriminating between as many as 10 million colors. so if you ever wanted to carry all your personal photos from your digital camera to show off this is awsome now you will need to buy the usb adaptor cable separetly so its best to buy at the same time. no Infrared...but the cable is cheap like 6 bucks...also you will ahve to buy a micro SD card up to 2 gb for storage.ok so what made this phone so above else is the sound of how loud it is...even when i hookup my jabra BT250v or BT150 its SO LOUD i have to lower the volume rocker ...and the speakerphone my god...also this run symbian s60 3rd edition so its really fast...compared to my last NOKIA 6230i...which had issues...but call quality was great...now the worst part...the batter talk time is really that reported 3 hours something....so if you talk alot get yourself a car travel or expect to at least plug in every other day...i love it mainly for that awsome internal screen...and sound quality..the camera was better then my cousins motorola razor but not as good as my old nokia 6230i...i know its 1.3 megapixels for all of them but for some reason they are not all equal....lets see if your Tmobile their version is the 6133 but its reported that it has 48 polyphonic sounds vs this version of 64. and this version doesnt have an fm radio nor a infrared. but if you want that then the 6131 european version has it...but its a european spec model so the battery charger is bulky and needs a 220 adaptor(cheap)well its a great phone and i think its also better then the sony w810i which i used as a loaner phone...speakerphone quality and sound quality could not TOUCH THE NOKIA 6126...I SWEAR IT...NOT TO MENTION the screen...couldnt come close...
