hi i have the samsung focus cell phone from at&t and when i want to download a free application it doesn't let me. So can someone please me. Well everytime i want to download like facebook for an example it says " can't get this info right now. Check back in a little while." I wait a while to download it again and it says the same thing. Please help me!!! Thank you.
