I tried this 2x battery app briefly this morning on my tbolt only to lose my 3g and wireless connection all together. I am able to connect to 4g but it's very spotty even in good areas. I have switched between mobile connections, restored earlier point, reflashed cm7 along with wiping and still nothing. I am looking for help, suggestions, etc as I've heard no response from developer, and don't want to deal with Verizon if not necessary. I appreciate any feedback as i know others have had to run into this.
