The R icon at the top of your screen actually means that you are using a Roaming Service on your network. It does NOT mean "Return" as the other person wrongly suggested.
i think it means it means that a message will be sent to there phone or they are on line from there phone
It means you have a missed call. If you ever don't know what an icon is again, go: MENU-> Settings&Tools-> Phone Info-> Icon Glossary. They're all there.
You have locked it and can't delete it only if you unlock it you can delete iy
its impossible!
It usually means you have an unheard voicemail. You can check your user's manual to find out for sure.
try hiding it or turning off your phone or resetting it.
Go to the iTunes icon.
a smartphone
you can't as the phone is to call someone and you cannot do that with an iPod touch
Press the Speaker On icon and when it says Speaker Off.....it is actually 'on' HTMS
When I had this problem on my phone I found out that it meant there was a new voicemail.
A touch screen cell phone may not recallibrate itself in a couple years of owning the cell phone. When trying to tap on the icon, it may tap another icon. The calliberation on it is terrible.
