I opened my Store app today in my C3 and was surprised that it was asking me to replace the 3.22.0 version with version 3.30.2! I pressed Yes and I got a warning "Application Source differs from original. Continue?", I pressed Yes again and my phone was downloading store app in under a minute.
Opening the app and going to Applications took a long time, I even forgot my password. I will be back again, but it really pays off to upgrade to the latest stable version. Some people simply use Nokia to avoid the insecurities in the larger Store App market for android phones!
