Low level Paladins able to use spellcasting based magic items?

[Kor - Orc Scrollkeeper]

Are 1st to 3rd level paladins (and rangers) able to use spell-based magic items. (i.e. a Wand of Cure Light Wounds)?

Under the Spell description section, is does indicate "through 3rd level, a paladin has no caster level."

This would tell me that they can not use spell-based items until level 4. (I remember hearing about a ruling under D&D 3.5 ed, that a level 1 paladin could use such a wand -- but I have not seen such a rule myself).

The 3.5 "ruling" is actually written into the SRD, which you can find here.

The specific rules for activating spell trigger items aren't in the Pathfinder Beta, so I would assume they haven't changed.

In addition to the SRD, it's also on DMG p 213. A 3rd level Paladin is specifically mentioned as an example of sopmeone who can't actually cast spells (yet) but has the spells on his spell list.
