Q: I lost my iphone 4 white I can track it by GPS lock or please give me the location

1. If you didn't activate Find My Phone, there is no way to track it.

2. You aren't addressing Apple here - this is strictly a user-to-user tech support site and no one here do anything to find your phone.

3. Learn to use punctuation and sentences so your post isn't a total pain in the a** to read.

This would only work if you have iOS5 installed, and you have activated the "Find my iPhone" feature.

If so, you clould log into iCloud and locate or remotely lock or wipe your phone.
