A new Nokia phone is getting ready to join the ranks of dust and water resistant phones. The new device - called Nokia 3720 (perhaps "classic" is not a wild guess here) - is IP54 certified, meaning it's dust and splash resistant.

The IP rating is an international certification that specifies the level of weather-proofing of any product. The first digit indicates protection from foreign objects - 5 in this case means that while some very fine dust might get in the phone, it won't impede its operation. The second digit is for the level of water protection - in the case of the Nokia 3720 it's a 4, meaning the handset is splash resistant.

We are also guessing there is some kind shock resistance, but at this point it's not clear how much exactly.

It has been quite a while since Nokia released their last dust and water resistant phone - the Nokia 5500 Sport. Back then it was running Symbian OS, but that doesn't seem to be the case with entry-level Nokia 3720. Even from this blurry photo it's pretty clear that we are looking at an S40 device here.

In the same time Samsung have released two modern ruggedized handsets - the 3G enabled Samsung B2700 and the cheaper Samsung B2100 Xplorer.

The rest of the information about Nokia 3720 we have is limited - it will be available in September in T-Mobile stores among others. We guess we'll just have to wait for subsequent leaks and the official announcement to find out the rest of the specs.
