I have a samsung moment, and have never received google map updates, but my sister has a mytouch and it keeps telling her: To update my Google Maps again it says: Your messages - read instant messages; Services that cost you money - directly call phone numbers. Along with several other things, like Your Personal Information - read contact datea, write contact data; Storage - modify/delete SD card contents, the your location and reading the phone state and identity. She's concerned about any extra fees, stuff being deleted off of her sd card, etc. Is there any concern for updating google maps???
