Has Anyone Experienced this Kind of Freezing???

Android here, but maybe something similar is happening on your i-device.

Last time TSTO would not give me the login (the normal things would not fix it), I went into the application manager and noticed that it was not installed on the sd-card, but was using a small amount of space there. Strange! So I cleared the cache and the data, and then uninstalled it. Then reinstalled it. That solved the problem with not being able to get logged in for me.

Could be it had nothing to do with it, but I'd run out of ideas.

Good luck!
