Currently I have the Blackberry 9310 for verizon as my 9930 broke... I want to try OS10 now after years of os7.1... Is there any app availability or difference in gaming between the Q10 and Z10... I can get either device brand new for 100 for someone I know... I love the keyboard but will I suffer from app availabily due to the smaller screen... Also is there a Social Feeds app like there is in 7.1... I like to post on twitter and facebook at the same time..
