i got the touchstone for christmas and it has been working great until recently when i charge it over night the battery will get to 100% and it will ding multiple times (as if someone unplugs it and plugs it back in repediatly) then it will completely stop charging and when I wake up it is at 40%.

2nd problem: notifications for my yahoo e-mail and twitter don't come up anymore, but texts do. The e-mail i have set to get it every hour and the twitter it is set on notifications. The e-mail now i have to manually go into the inbox and hit the refresh icon that is the only way my e-mails come through.

If anyone can please help it would be greatly appreciated.
