G1 phone is locked due to wrong pattern,with no service to sign.

Try turning your phone off and removing the battery. Wait a few minutes then reinstall the battery then try again.

G1 is an american branded phone ( GSM 850 / 900 / 1800 / 1900) , It wont work on all service providers across the world .. You might want to put another service providers sim card ...

You will need to reset the device.

1. Power off the G1
2. Hold Home Key + End key for 20 seconds or until you see a "triangle with an exclamation point and a picture of the G1"
3. Open the QWERTY keyboard and hit Alt+W
4. Restored!

Your IMEI numbers are needed to unlock your HTC G1 mobile phone. Reveal the codes by pressing *#06# on your phone keypad. Then after getting the information, please go to an HTC UNLOCK CODE website for you to be provided with the correct codes. You also may need to know the country and network the phone was purchased from. thanjs

i would recommend ordering a new SIM card from your cell phone provider. good luck with this issue! hope this helped!

Ok, So I just had the same thing happen to me last night and I just fixed it. It'll take 2 people to do it. I went on to my gmail and changed my pattern, after a few minutes my phone had a triangle with an exclamation mark come up in the notifications bar. Don't bother turning off your phone...mine didn't reset for the pattern after 7 hours of being turned off. At this point, once you get that triangle, get someone to call your phone, it'll unlock it for a few minutes. Just long enough for you to change the password on your phone by clicking into that arrow. Then your phone will lock again after the call is done. Put the new password into your phone again on this screen. Then it'll ask you to draw another pattern. Draw something simplistic, then if you want to take it back off just go back into your settings and remove the lock....just remember your pattern this time! hope this helps!

Exactly how are you locked out? If you're stuck on the lock-out screen with a lockout pattern that you've forgotten? If that's the case, the G1 manual indicates the following:
"When you fail to draw the correct unlock pattern on the screen after five attempts, you will be prompted to wait for 30 seconds before you can try again. If you forgot your screen unlock pattern, touch Forgot pattern. You will be prompted to sign in using your Google Account name and password, and create a new screen unlock pattern before the Home screen displays."

maybe you should sell it or get a new one or fix it

Right now the G1 is having issues logging into the phone after you get locked out using a screen pattern. Just try to remember to write down the username and password you used the first time that way you won't lose the information on your phone by having to reset it. Also make sure you are typing it carefully and make sure to enter your whole gmail address too (Ex. [email protected]). Also if you have had to change your password from a computer after you logged into your G1, it does not take the password change. A way to avoid that is to login to the G1 again. Sync your contacts to gmail first (Settings > Data Synchronization > Menu > Sync Now). Then go to Settings > Applications > Manage Applications > Google Apps > Clear Data. To sign in again go to Settings > Data Synchronization and it will give you the option to create an account or sign in.

Attempt to enter the lock pattern 5 times.
Wait 30 seconds, then tap "forgot pattern?".
Enter your Gmail account name and password.
Sign in!
