hello all.... I apologise in advance if these questions have been asked and answered in previous posts, but i've had a trawl and couldnt find anything. Firstly, ive only this week bought and received an acer a500 32gb tab... and i love it....... however...... i'm having real teething problems with a few aspects of the tab..... this is where i could use your help.... 1. I cant get a usb flash drive to 'show' on the tab.... ive formatted the usb pen which is 16gb, made sure it is FAT32 and still nothing.... what is wrong? 2. wifi tethering..... am i right to say that i would need to 'root' my tab in order to connect it to the 3g service on my mobile phone?.... which leads to my final question..... 3. if i root my tab, is there a chance i can irrepairably mess up my tab.... and in fear of this, how can i back-up my system so that i can reset it if all goes wrong Again.... sorry to ask what might be deemed as stupid questions, but ive been using windows mobile OS for years now, and am at a real loss when challenged with the complex setup of the android OS!! Thanks for all and any help!
