I am lumping this all together in one post, but be forewarned, it’s lots of information. But I know everyone is curious where they will be able to watch the Hope for Haiti telethon and wondering which Twilight cast members are involved and will be answering phones. Click through for all the details I have managed to gather.

So here’s what we know:

Who’s in:
Rob Pattinson will present from London, and it has been said he is hosting the London branch solo, but also that he will be manning the phones. You can read the article People.com had about him answering telephones.
Anna Kendrick will help out from the US base (I assume it’s in Los Angeles), and while I don’t know what she’ll be doing, my guess is answering phones.
Rachelle Lefevre will be involved in the Canadian fundraiser which will air just before the George Clooney-organized one.
Tinsel Korey will help out as MTV’s online correspondent during the fundraiser.

Who’s not:
Taylor Lautner, Kristen Stewart

All dona­tions will directly ben­e­fit Oxfam Amer­ica, Part­ners in Health, Red Cross, UNICEF and Wyclef’s Yele Haiti Foun­da­tion. Face­book and MySpace have signed on as offi­cial social-media part­ners to help steer view­ers to the telethon and drive donations.

Addi­tion­ally, the Clin­ton Bush Haiti Fund and United Nations World Food Pro­gramme have joined the list of relief orga­ni­za­tions that will ben­e­fit from the show, with pro­ceeds to be split evenly among each organization’s indi­vid­ual Haiti relief funds. “Hope For Haiti Now” will be the most widely dis­trib­uted telethon in his­tory, inter­na­tion­ally and across media plat­forms, includ­ing live stream­ing glob­ally on sites includ­ing YouTube, Hulu, MySpace, Fan­cast, AOL, MSN.com, Yahoo, Bing.com, BET.com, MTV.com, and Rhap­sody and on mobile via All­tel, AT&T, Sprint, Ver­i­zon, and FloTV.
