A potential solution: Before I got a true smartphone I had a Nokia E71. It had an OK browser, 3G and you could even tether via Bluetooth. As it was Symbian&#x2F;S60 there were some apps like Google Maps, but switching apps was a pretty painful &#x2F; slow process so you didn&#x27;t want to do it often. The battery lasted about 3 days even with regular usage.
