Problems on iphone 3GS after upgrading to IOS 6.1.2., Problems on iphone 3GS after upgrading to IOS 6.1.2.

Hello all,

Some urgent help needed on the 3 problems listed on priority basis, as follows.

P1 -> I upgraded to IOS6.1.2 on my iPhone 3GS last week and all worked fine for 2 days. Then, last Thursday (21st February) evening, the mail app started crashing and is currntly unusable. All efforts to Restart/Reset, have failed.

P2 -> With the SMS app, there is no sound/vibrate available, whenever a message comes in. Pretty annoying!

P3 -> There is extremely heavy battery drain, resulting in the phone having to be charged atleast 4-5 times a day.

On the upside, after the upgrade, the phone works really fast.

Could any of the gurus over her, offer any help or insights please?

Thanks & Regards,
