Too many pattern attemts - Sony Xperia Tipo Dual ST21i2 Black Android 4.0.3 Dual SIM unlocked phone

First solution is to use Google account associated with mobile.You need to log in into your Google account and then you can disable or change the pattern lock.

Second solution is to boot into recovery mode and reset the tablet - you will loose all you data however.

The third solution is only for techies and involves using the Android debug bridge to reset the tablet - not for the faint hearted.
