I went to this T Mobile location to use their jump program to upgrade to the iPhone 6.
The woman who helped me informed me that I would have to use cloud to transfer my information. In the past at other locations they have been able to sink the phones immediately. She said they were unable to do that anymore. I had never used cloud to back up my phone and it was going to take hours. In an attempt to find a solution I asked her if I could take my old phone to the Apple store and have everything handled that way and she said I would need to then send my old phone to T Mobile. I asked her if once I had the new phone if I could just drop the phone off at the store and she said no. After more questioning she informed me that some T Mobile locations can sync the phones instantly but that store doesn't have the equipment. I asked her which was the closes store that would be able to synch the phone and she said she didn't know. I asked her if I uploaded everything to cloud if I came back the next day if they could sync it in the store for me, she said if they had any phones left. I explained to her that I really wanted to do the sync in the store in case anything went wrong and confirmed with her that they would be able to sync it if I uploaded everything and she said yes.
So at this point I really should have gone to a different T Mobile store but this one is very convenient so I uploaded everything to the cloud that night and went back the next day. The same woman was the only person working in the store the following day (I was really hoping I would get someone else but no luck). I told her I had uploaded everything to cloud and asked her if I could upgrade and sync the new phone in the store. She erased all the data from my old phone and boxed it up, and then began the sync on the new phone and it said it would take 3 hours! What was I suppose to sit in the store for 3 hours while it synced? When I brought it up she said that sometimes it takes a little bit. 3 hours is not a little bit, 15 minutes is a little bit. I ended up without a phone for the afternoon and had to sync it from home later in the evening.
