My iPhone keeps telling me I have no storage?

Since this message was initially delivered to me I've deleted half of my 3000 pictures (now at 1395) and am now down to 40 apps (deleted about 10). Also, this started when I synced the phone number on my iPad to the one from my phone and that caused a whole new scene but I've changed that and my storage issue hasn't gotten any better. Also, my phone takes about 5+ minutes to send any text or iMessage - if anyone knows the solution to that? My phone has issues.

This happens went you stack lot of date on the iPhone. For speed issues, best is reset to factory defaults and wipe everything.

This can be hard losing all the stuff. Other can be using additional storage and quick transfer device for iphone like this one - http://www.stuffselect.com/ipad-flash-drive/
