I am having a bad experience with this phone.
I used this phone for 6 months charging is worst and no battery backup it comes only 3 to 4 hrs of charging.
In travelling cases we cont carry this phone and some applications wont support this phone and it takes a lot time to browse for dowloading apps it is quit different every one wil confusing to use this phone .I am really feeling bad about this phone.
In my opinion dont buy blackbeery z10 .
