wonder when WP will announce Instagram .... miss this apps badly

i got trouble with my Lumia 920 yesterday night, phone sudden freeze screen and all button failed to function at the same time, black screen and only NOKIA wording...i cant do anythg and just wait the battery drain empty then restart the phone....this is the 3rd times d...should i send back to NOKIA??

i don't know got soft reset, will try if freeze again...

I just realized that the screen easy to get frozen when i watching youtube via metrotube...it's been happends few times for me already...

Anyone here face this problem also??

Window store market update very slow, no instagram, less game which IOS have...bored >.<

Battery life really a big problem for me even closed all the background apps and body heat up very fast
