They are not that stable. If this was an issue they should require a wited connection. And in fact they should get rid of the problem entirely by downloading to an sd card, verifying that the download is complete and uncorrupted, ad then updating from the card. Being able to turn off this infernal notification would be nice too. And seriously, if it can brick my phone, wifi, hard line, or mobile data, why am I being harrassed into taking this risk?
