I'm aware of four ways to add Jump to a Bard's spell list:
1. Play a Samsaran and take the Mystic Past Life alternate racial trait to add spells from any arcane spell list to your class's spell list.
2. Play a Magician, a bard that focuses on magic.
3. Take Skill Focus (arcana), Eldritch Heritage, and Improved Eldritch Heritage to gain access to the level 9 Arcane Bloodline power, which would allow you to add wizard spells to your spells known at 11th, 15th, and 19th level.
4. Buy a Ring of Spell Knowledge, which would allow you to cast Jump as a second level spell.
5. Ask your GM to let you learn Jump when you level. If you need a rules justification for this, see "Adding Spells to a Sorcerer's or Bard's Repertoire" on this page, which says sorcerers and bards can learn "new and unusual spells they come across while adventuring."
I like the fifth option the best, as it seems unlikely Jump will break the game, especially if you're playing at levels where many characters can fly or teleport.
