Hi Forum ! I am planning to buy a Reliance connection with P3000 h/s.I need to know from current users the following- 1) What down load speeds can I expect with this phone? (Avg,minimum,maximum) 2) Does this phone have a RUIM? Reliance CC guys plead ignorance on RUIM feature on P3000. 3)Any other pros & cons of this phone compared with S720? 4)Can I use the RUIM enabled phone on Tata network. Hoping to get loads of help for making a "buy" decision!!!!!!!!!!!!!!!!!! Thanks
