First I know people shouldn't use apps like this. I use them literally a couple times a month for a few minutes and am not being stupid with them. I don't try to replace my home Internet etc. My usage is a gig or so a month total for my phone so spare me the bit about ruining things for others. Its not me that blasts the data through non stop. Anyway with gb I had missed my tether. Wireless tether had failed me and I didn't want to flash the patch. I tried it again with 602 and no go. On a whim tried barnacle and Tada it works beautifully.
