The main Confusion Starts when, someone thinks to buy IDEA Blade. Specially in India right now there are two rebranded versions of ZTE Blade are available, one is DELL XCD35 and second one is IDEA Blade. DELL XCD35 launched in the middle of year 2011,initially DELL XCD35 sold as GEN1 Blade, with 512 (H/w) RAM but only 256 RAM unlocked means Practically only around 160-190MB RAM for use, but late November DELL starts Shipping GEN2 Blades with complete 512MB RAM unlocked,
But in case of IDEA Blade, this Blades are GEN2 Blades, but the actual h/w RAM is 512 or not is not revealed yet , till date IDEA Blades comes with 256MB RAM unlocked i.e. 160MB to use.I'll update you guyz as soon as i found out the truth, if IDEA Blade also has 512MB H/w RAM we can unlock full 512 RAM by (Total Phone Transfer)TPT Flashing, you can refer this link for details.
So stay tune for more updates... !
