I've done a few searches in the forums here and not found a solution that worked, so I'll try here. I have only had my phone for about 4 days now. I switched carriers from a budget carrier (cricket) to T-mobile. I manually entered in all 300 of my contacts. It took about 3 hours. I had yet to save my contacts to my sim card, as i damned well know i should. When entering these contacts into the phone, I used the default setting of T-mobile Contact Type when saving these contacts to my phone. Well last night i received a text message from a friend who was already entered into my phone. I was in the middle of a conversation, talking instead of paying close attention to what i was actually doing.... I added the person as a contact, deleted her old profile with the wrong phone number, and re-linked this profile to her facebook account. It did link her as well to an email account that was not hers. I saved the account and went back and removed the link to the wrong email account. Everything seemed fine. I went to send another friend a text message, and when doing so, I noticed ALL my contacts were missing except for a few which were saved to "PHONE" instead of "T-Mobile" When looking at the contacts list, my "T-Mobile" Group is completely erased, with the exception of the single entry i made earlier in the evening. I have gone back and tried to sync with T-Mobile under the sync page and nothing happens. I've played with the sync options and I can not seem to find these contacts ANYWHERE. I'd really rather not spend another 3 hours entering in all of these contacts... Does anyone have any idea or suggestions on what i might do to find these contacts or are they long lost forever? Thanks for any help you can provide. If and when i do go back and re enter all my contacts, should i save them to Tmobile, Google, or Phone?
