Mashable is currently in Miami, where two lucky readers and event attendees will have a chance to win tickets to South by Southwest. Later this week, Mashable is headed to Boston and then New York City.

During each of these SummerMashes, attendees have a chance to score some sweet tickets to Austin’s hottest interactive festival: SXSWi 2009.

Yesterday, the SXSW Interactive website relaunched with all-new artwork and site architecture. Also, yesterday was the first day that you can purchase a registration for the 2009 event. Remember, the earlier you register for the event, the lower the price to attend. Registration early also gives you the most possible downtown lodging options. In other words, book your room now via the SXSW Housing Desk before your hotel of choice sells out (and trust me, they will!) The 2009 SXSW Interactive Festival begins Friday morning, March 13 and ends Tuesday evening, March 17.
