Hello friends,

This post aims to show the stark reality as regards to firmware 3.1. It is true that has been presented as the firmware that will solve the problems they had in the iphone, such as battery life, security holes, etc.. The reality is different, however, since there has been a problem increase as the duration of the battery and overall concerns about the GPS.

While we can say that any user, including an editor of this post has made substantial improvements and better performance note of the terminal, many other users who have found they have lost effectiveness in its battery, up to 25% less and above all, and lived in my flesh in the first person with the GPS location problems.

After consulting on many boards and Apple, yes friends yes, officers, and astonished to see no apparent explanation as to the disappearance of the GPS signal suddenly or even no phone detection by satellites, we wonder … Why we have upgraded to 3.1 without first going well?

Well friends, finally we found the solution, not trivial, it has been to make the downgrade to 3.0.1, which we have recovered the efficient positioning again and the battery lasts at least a couple of days.

To get the process tedious and time consuming but not impossible to return to the 3.1, you can consult the tutorial we put about Downgrade firmware 3.1 a 3.0
