Responding to comments when mobile needs fixing!

I just spent a week using BrightKite while entirely mobile via a combination of the iPhone app and SMS messages. It became apparent that when friends comment on my posts, it is almost impossible to respond to them in the app.

My workflow was as follows:
1. Post a photo or note at a place from the iPhone app
2. Receive an SMS message indicating a friend commented on my post (from 1 min to one hour later)
3. Attempt to respond to the comment but am unable to easily find my post due to my stream being filled with posts from others, etc.

This used to be mitigated by clicking the link from the SMS message which opened the bkite app and displayed the post (no longer working). Now I either have to open the webapp (which I'm usually not logged into) or find my desktop to get to my thread.

There really ought to be a way to respond to comments more easily, I can think of a few ways to do this:
1. Fix the link in the SMS message to show the comment in the app when clicking the link
2. Make it possible to see only my personal posts in the app
3. Allow me to make a comment via SMS (similar to when I get a direct message)

Hope this helps, I think making it easier to have a conversation around posts would do a lot to improve the community feeling!
