My Samsung Galaxy S2(I-9100) was upgraded to 2.3.6 by the technician at a Samsung Service Station. This resulted in a wiped-off of all the apps that I had installed along with some other data(like contacts,sms etc).
I had to go through the entire procedure of registering your phone with my gmail account.
I cannot install some of the apps that I had previously installed (from the web store) because I cannot choose the device and I get the message "Your device already has this app installed".
Any help would be appreciated.
