[quote author=“rahulnirmal2000”]Isn’t it true that the T2XX and T3XX series use a different, slightly higher capacity battery than the ones on the T1XXs and they aren’t intercompatible with each other?
Also, is the antenna on the side of the T3XXs removable and is it only used for the EDGE connections? I know very little about computers, but I thought it would also make the Wifi radio perform better as well but I’m probably wrong about that.
I wish someone could make a very comprehensive and detailed T series faq like somebody did on the U series.
You might be right about the battery. The VGP-BPS3A entry on Sony’s page only mentions the T2xx and T3xx models.
The WiFi antenna is in the bezel around the top of the screen, AFAIR. It’s optimized for 2.4 GHz (BT & 802.11b/g) and 5.4 GHz (802.11a) frequencies rather than the 1900 MHz (and possibly 850 MHz) frequencies Cingular uses, hence the additional antenna.
