ouch! sorry Maeomo, but you had that one coming. The different states are showing what type of connection to the mobile network your phone is getting - it's heavily location dependant, so will change depending on whether you re in a city or countryside, and whether you are in/outdoors etc. Bigger the number, faster max data rate you will get (and more oyur battery will get bled dry).

I seldom LOL (or feel the need to exprss it) on a forum, but "That one Guy" - that link was a real work of art :-)
