Just download the new 2go v4.5 www.2go.co.za if you are using android or java but if you arent visit www.2go.co.za with your operamini,click on option and click on enter address,now go to the end of address,you may see something like this www.2go.co.za/2apwm1wn then add this at the end of the link /change.php and change whatever of you want to change,believe me it work
