ENERGY ROM:
http://forum.ppcgeeks.com/showthread.php?t=113971 This ROM are great, maybe you will feel a little bit astonished with all kind of new information. Google a little! I recomend you to use 23569 Sense 2.5 (
http://depositfiles.com/es/folders/5S05PEBIP) With this you will have Windows mobile 6.5.3 and HTC sense 2.5 with a lot of extras!
5. Download the file, extract the whole foder and open a file called "Bootloader" (if my memory is right) and follow the instructions.
6. After that you will see be first time the tricolor screen! When you finish the cellphone will automatically reboot! I recomend you to do a hard reset (Power off you phone, and press red, green an vol down button at same time until tricolor screen appear, Press volup to restore manufacturer default and and send key to confirm! VOALA! You have a new phone now!
7. Please be patient with first boot!
8. Now conect you phone in ActiveSync and restore your contacts with MyPhone
9. Remember, in order to use the internet from AT&T you need to create a new connection. First call AT&T and ask them your internet settings like: Access point name, user name, password, domain. When you get that go to Start/settings/connections/connections choose Add a new modem connection, call it AT&T or something, choose cellular line (GPRS, 3G) option and configure it like AT&T told you! After that choose manage existing connections and select you new connection as default! Now you should have AT&T internet by EDGE no 3G (There's no way to get 3g because frequency incompatibilities)
10. These are other settings I recomend you: If you dont use Internet, FB or twiter tab remove them in order to save some RAM. In Start/Internet/Data controller/menu/configure connections timeouts you can close your connections after X time of inactivity, this will be your best friend with battery life! I have 1 minute. I recommend Opera mini as your default browser for people without 3g (You and me!).
I thinks that's all! Remember to hit thanks!
