Dear Friend,>If you use Gmail with your Google Account, it's not currently possible to change your Gmail username after you've registered. You can, however, create another Google Account with a different Gmail username.
>To change the email address on your account, just follow these steps:

1. Visit the Google Accounts homepage.
2. Sign in to your account.
3. Click the Edit link next to 'Email addresses.'
4. Enter your new Google Account username and your current password.
5. Click Save.

>Here's how to remove an alternate email address from your Google Account:

1. Sign in on the Google Accounts homepage.
2. Click the Edit next to 'Email addresses.'
3. Click Remove next to the email address you'd like to remove.

If this Helped you RATE me...thanks For Contacting FixYa....

Hi there,

If the phone is unlocked then you shoudl not have any problems, besides, the G1 unlocks automatically after 90 days or at least the UK T-Mobile version does. If you don't want to use 3G then make sure you turn it off in the wireless settings.

If you cannot remember the username and password to your G1, there is not a way to recover it at this time. The only way for you to have your phone again is to do a master reset using the hardware buttons. This will delete all of your data on the phone only (SIM card and memory card data will be fine). To do a master reset power the phone off completely. Hold the home key and the power key at the same time while turning it on again. You will see the T-Mobile G1 screen first, but them you will see a screen with a triangle appear. You can let go of the keys and open the keyboard. Press and hold the left ALT key and then press the letter W. Release both the keys and the phone will power off. Then it will power on again and act like you just removed it from the box. Create your new account and write down the username and password this time that way you wont forget it.

Here is how to set G1 3G and MMS for UAE Etisalat separately (u can enjoy mms or 3G alone by deactivating settings for either one). First you need to setup 1 access point for each service, sttings is as follows:
-----------------3G----------------
Name: Etisalat3G (could chos any name)
APN: Etisalat.ae
-

--------------------------MMS----------------------

Well if you have updated your iphone then the sim will not work because the new software prevents from hacking or using other sims than at&t.
