[Blindtlk] Most accessible iPhone version?

[Lucy Sirianni]

Hi everyone,

I'm going to be purchasing an iPhone this weekend and had a quick 
question before doing so.  I'm assuming that the newest available 
version is the best but wanted to be sure that's in fact the 
case, as I know that updates don't always take accessibility into 
account.  Would folks here recommend going ahead and purchasing 
the latest version, or is there an older version that's actually 
preferable in terms of accessibility? Anything else I should be 
aware of?

Thanks, all!

Lucy
