im looking at buying a time capsule but im looking to get the last years 500gb model MB276LL/A since i already have a 500gb western digital hard drive im looking to hook it up to the time capsule so i have 1tb total. anywho.... what im wondering if this model mb276ll/a will do the dual band support the new 1tb and 2tb models have? i have looked everywhere to find an answer but have been stumped any help would be much appreciated. ive looked at apple.com and looked at both time capsule manuals for early and recent time capsules and they both indicate that they both do the dual band i just want to make sure thanks
