Spb Mobile Shell has been a UI replacement for all us Windows Mobile guys for a very long time. It may have lost a little bit of market share with sexy HTC Sense, but it has been continually updated and is a super nice alternative to CHome or HTC TouchFlo 3D (Sense). SPB Mobile 3.5 has done a great job in utilizing 3D Graphics to really make Shell more appealing without sacrificing speed and stability. And it looks like SPB has no intention of stopping progress with Mobile Shell either. At MWC (Mobile World Conference) in Barcelona, SPB plans on announcing SPB Mobile Shell 5! Jumping from version 3.5 to version 5 is a good indicator that we are going to see some really nice advancements too, so I am pretty excited to see what SPB Mobile Shell 5 will have in store for us. My hope is that it continues to lighten the memory usage unlike HTC Sense 2.5 likes to chew up. In any case, check out the Ad that is circulating and hold tight as we wait for the announcement to happen at MWC!
