hi i have the iphone 3g with 3.0 beta 5 i updated the carrier file in beta 4 so i can still do mms with my beta 5. i have an icon that i noticed the other day and i have no idea how long it may have been there before i noticed it. it is on the top next to the icon to let u know of set alarms and the battery status. it looks like i phone reciver laying face down over 7 dots under it. i havent seen it on anyone elses phone nor in any pics i can find on the web with other peoples phones using 3.0 beta. does anyone know what this icon is?
