Excerpt: I had this phone for about a year and experienced the same problems described by other disatisfied users on here (Low memory, long waits for text or menu navigation to catch up, inexplicable call drops) when it finally started just freezing completely in the middle of calls. I would pull the battery to reboot it and that worked for a while. Then it stopped recognizing the SIM card. I got my data transferred to a new SIM card, but it still did the same thing.
Excerpt: This phone would be a fantastic little device if it weren't so slow. Do yourself a favor and if you buy this phone with the T-Mobile Fav5 software on it, flash it with the Cincinnati Bell firmware (and of course change the right settings). Doing this will speed the phone up and unlock more features of the phone. You can manage your Fav5 contacts from T-Mobile's website.
Excerpt: I have to say, I LOVE my phones theoretical capabilities...but thats it. I have had this phone since Christmas and am now on my 3rd unit. Battery life is excellent as is the reception. Sound quality from the mp3 player is outstanding for the size of the phone. Easily heard throughout a moderately quiet room with excellent quality. The software on the other hand is lacking. The interface is a crisp screen with slow software that will make the feel more like a smart-phone.
Summary: I got this phone a few weeks ago after using a blackberry pearl for several months previously, so take everything I say with a grain of salt if you are still used to older phones. However even a lot of older ones work a lot better than the T610. When trying to change from one menu to another the process is oftentimes achingly slow.
