Hey I bought some 'elite screen cleaner' from a company called ULTRA. the guy at the electronics store I bought it from said it was fine on the G2 but I wanted to make sure so I emailed the company and he said there is not for sure testing on that particular cellphone model. But said he cant see any reason for concern on still using it. Its alcohol and ammonia free. and its a gel according to 'liquid type'. water <96% and it comes with a nice microfiber cloth too. any thoughts?
