i have a very old Motorola phone which I only use for occassional texting and very occassional calls. I have ipod which I use for internet quick stuff (like this
) and pay for internet via BT phone bill.
i have always been on pay as you go with Orange - i have text from Orange on Tuesday confirming my latest top up
I am confused though as on Home screen where it used to say 'Orange' (least I think it did) it now say 'T Mobile UK'. 
Did TMobile change to Orange? Have just asked DD what hers says as she is Orange too and she says hers says T Mobile 'sometimes' too?
Am I missing something? Not really sure how mobile tariffs work as always been pay as you go - am I randomly using another net work?
Is it switching itself to better reception or something?
Nothing weird going on and Im going to get bill from T Mobile is there?
Sorry if this is stupid question but not at all 'techy'
