I just bought the T610 and have been disapointed so far. The charging circuit in the phone doesn't work properly (never confirms that the battery is fully charged, even after 8+ hours of charging.) But more important, the phone's reception is very poor! I live in the Seattle area. Once in a brief while, I show all 5 bars on the display, but more often it's only 2 or 3, and a weak 2 or 3 at that. My wife bought the Samsung E105 at the same time. The side-by-side comparison is very interesting. Her phone shows 5 bars (and gets great reception) most of the time; we're both on T-Mobile. I bought the T610 primarily because I wanted Bluetooth, but it's not worth it. My recommendation - steer clear of the T610. If you buy it, I think you'll be disappointed too.
