How to extend Wi-Fi range and coverage?

My Belkin Wi-Fi N router will only cover half my house. Its located in the bedroom, the sitting room is on the other side of the house. I don't get a single bar on my iPhone or laptop.

My iPhone 5 won't connect to 3G?

For the past two days the little '' 3G '' symbol at the top of my iPhone 5 hasn't been there - then I realized that it meant I couldn't text or use the internet on my phone. I have turned my iPhone off and on, taken the sim card out and put it back in again and reset my network settings, but nothing has changed. I also went into my phone settings app>general tab>mobile data>, and it said that my 3G was '' On ''. I just don't understand why it isn't working. My phone is currently on '' Vodafone NZ '', and I have only had the phone since November 2012.

IPhone 4 or Nokia lumia 900?

Need a new phone for phone call, text, twitter and browsing website. IPhone 4 are good but all over the street, on the other hand, Lumia 900 gets low screen resolution but prettier look. So how can I choose?

P.S. Lumia 920 and iPhone 5 are perfect but out of my budget. And I don't like android phones.
