All four of these phones have had their fair share of leaks, but now HTC is ready to fess up and assign some names to their Q4 lineup of phones, which is all set to bust up on Europe this fall. Starting from the left we've got the S3300, codenamed Artemis, which is due for an October launch, and features TomTom software to power the GPS action, along with a 2.8-inch screen and a snazzy new "RollRTM" trackball / track wheel. The P3600 (aka Trinity) picks up where the Prophet and Magician left off with a bit of bulk, some cute looks, but sadly no QWERTY action. The phone does, however, manage HSDPA speeds and a 2 megapixel camera, so it won't be all tears when this thing drops in September. Next we have the Q-killin' "Excalibur" S620, which measures a mere 0.5-inches thick, weighs 4.6 ounces, and manages that lovable QWERTY keyboard and 2.4-inch screen. The phone, due for an October launch, will also come with quad band GPRS/EDGE (3G is conspicuously absent), WiFi and Bluetooth connectivity. Finally, HTC's S310 "Oxygen" candybar isn't anything too terribly interesting, but it's a nice new look for HTC candybar fans who found the HTC Breeze to be a bit too squarish. The S310 should be out this September. Possibly the best news among all this action is that it seems HTC has decided to abandon the frightening naming convention they adopted for the "TyTN" and "MTeoR." That was a slippery slope if we ever saw one. The worst news is, of course, HTC is only self-branding these phones in Europe right now, and will be letting US carriers adulterate these phones with garish branding and spec drops before we ever get a chance at 'em. Oh well, such is life. Keep reading for entirely-too-large pr0n of all four phones at their shiniest.
