Unfortunately, SnapTell Explorer crashed and froze several times during my testing on iPhone 3G 2.2. These crashes and freezes could not be duplicated and seemed to happen at random. One freeze required a hard restart.
When it wasn't crashing, SnapTell Explorer admirably recognized two books and a comedy CD, each from a simple iPhone photo. Though it did crash frequently, the recognition portion of the software worked wonders.
Version 1.1 is the second version of SnapTell Explorer, and SnapTell, Inc. promises a new version is winging its way through development. Once the crashes subside, SnapTell Explorer will be very handy for holidays, birthdays or any shopping in general.
