I had a 1.1.2 with 3.9BL jailbroken and unlocked.
I decided to upgrade to 1.1.3 using soft metod (used the most recent hackthatphone guide) and then i upgraded the baseband to 4.03 using the iclarified tutorial (i wanted to have the GMaps features working).

Now the phone says that i have a 1.1.3 firmware with 4.03 BB. icons wingle, so i am definetely on 1.1.3.

What's wrong then, you may ask?

Well, it looks to me that the applications on the springboard have not been updated. Safari does not have the + bottom to add icons to the springboard. non multiple sms. GMaps does not have the locate feature and crashes 2 seconds after launch. calendar crashes. recent calls menu crashes the phone.
Plus i have stuff on the springboard i canno t see in the installer and therefore cannot remove.

Do you guys know whether there is a fix? i cannot find anything in the other threads.
In case how would you suggest me to undo the 1.1.3Firmware+4.03BB upgrade to start it all over again?

help is really appreciated
