if you have a symbian phone you can install an app that blocks unwanted texts or calls, gamit au na sa mga spammer feeling sikat cigeg GM... and then.. you can also have an sms bomber app to counter attact that person. pwde nimo spaman ug endless text messages in just one click, walay kapoy. and the best thing is, maguba ang celphone sa recipient especially if low to mid end phones kay d makaya sa ram ang mag sunod2 nga texts, murag ma overheat or ma not responding kung sa pc pa.. hehe
