Hi there, ok I have a Samsung galaxy s2 mobile and although great android phone the signal is bad for logging onto net, yes I know its the service provider, im with vodafone and I get one bar when I take my phone to work, problem is I work in a control room so basically the signal is very weak im lucky if I get 3g and one bar, im on auto settings for signal ie gprs/gsm. So when I switch from wi-fi to my data pack this is when the signal is poor, as for the wi-fi great in the house but non-existant in my work, no network coverage at work wotsoeva, so not happy, have a great phone but cant access net, so looked into this sure signal box, gave vodaphone a call but problem with this is you need to plug this into a modem of such and alas im not allowed to do this at work so cant use this, can I upgrade to g4 will this guarantee me a signal or is this really for download speed, so people help me out here, is there any program out there that can enhance the signal.
