Because the PR update will be in last week of July of in the Mid of August and it occurs in the time duration of 3-4 months so just wait and collect some good quality links for your site in this time duration..........and then u will surely get PR if you do work better and relevant.
better get some higher PR sites in your back links.. hmm it will update about 3 months or less than 3 months..
Even if you start building links now you will get a PR on the next PR update (expected sometime in September).
Start your link building fast !!!! You can get high ranking in next update ! i.e, with three months !
Pagerank is not important. Conversions are what's important. The little green bar in the visitors toolbar won't pay any bills for you. Focus more on building your inbound links based on solid keyword research. Next watch your SERP positions as you get indexed, and see if your most sought after keywords are performing for you. If not, adjust your text copy on your page for stronger keyword weight, or better yet, keep working on those inbound links.
Submit to free article directories. The links get picked up quickly and they are often given more weight because they are contextual links. Find a few good directories like goarticles.com and buzzle.com. And add some social bookmarking buttons to your best pages so users can do your link building for you.
from what i know the google PR updates every 3 months. get back links. better if it is relevant to your site.
