Do not download new mxit from anwhere but the official mxit website. Yes, it might look good but the non official mxit could be used to steal your personal information and could be sold to companies that will spam your inbox!
If its not from MXit.co.za, its not the real thing. Not yet anyway. Unofficial versions are not supported by MXit.co.za.
they want mxit to kick ass, but it takes time 😉
Until MXit say the reskinned ones are fine (or you read it here) DO Not download from anywhere but MXit.co.za!!! Danger Gevaar Ingozi.
