Well i am having Sony Ericsson handset. Recently i have upgraded with 2.1 version of the firmware using the PC companion. Well i have found that the upgrade process is seems to be working fine and there was no trouble while doing the same. after finishing with upgrade i have found that the apps were unable to load on the phone of mine. i have searched on the Google but it did not help me to fix the matter of mine. Any help on this particular matter would be highly appreciated. Thanks a lot in advance.
